Client–Server Model

/ˈklaɪ.ənt ˈsɜːr.vər ˈmɒd.əl/

noun — “the digital handshake that keeps your apps and servers from fighting over data.”

Client–Server Model is a network architecture where tasks and workloads are divided between service providers, called servers, and service requesters, called clients. In this model, clients initiate requests for resources or services, and servers respond by providing data, computation, or functionality. This separation allows multiple clients to access shared resources efficiently while centralizing control on the server side.

Network Protocol

/ˈnɛt.wɜːrk ˈproʊ.tə.kɒl/

noun — “the rulebook that keeps your data from turning into digital chaos.”

Network Protocol is a standardized set of rules and conventions that govern how devices communicate over a network. It defines how data is formatted, transmitted, received, and interpreted, ensuring that different systems, operating systems, and applications can exchange information reliably and efficiently. From sending a simple email to streaming high-definition video, Network Protocols are the invisible traffic controllers keeping everything orderly.

Network Port

/ˈnɛt.wɜːrk pɔːrt/

noun — “the digital doorway your data knocks on to get where it’s going.”

Network Port is a logical endpoint in a computer or network device used to identify specific processes or services within the system. While IP addresses locate devices on a network, Network Ports ensure data reaches the correct application, whether it’s a web server, email service, or custom program.

Network Stream

/ˈnɛt.wɜːrk striːm/

noun — “the virtual water slide that carries your data across the network.”

Network Stream is a continuous flow of data transmitted over a network between two endpoints, typically using protocols like TCP or UDP. Unlike batch transfers, Network Streams send data as a steady sequence of packets, allowing real-time communication for applications such as video conferencing, online gaming, and live media streaming.

Socket

/ˈsɑː.kɪt/

noun — “the doorway your data knocks on when it wants to leave the machine.”

Socket is an endpoint for sending or receiving data across a network, allowing programs to communicate with other programs either on the same machine or across different systems. In operating systems and networking, a Socket represents a structured interface between an application and the network stack, abstracting away the gritty details of packets, routing, and hardware.

Virtual IP

/viːˈaɪˈpiː/

noun — "Very Important Packet, because some traffic deserves the red carpet."

VIP, Virtual IP, is a network concept where a single IP address represents multiple physical devices or servers. It allows load balancing, high availability, and failover configurations by routing traffic to the best available resource without clients needing to know the underlying infrastructure.

Throughput

/ˈθruː.pʊt/

noun — "how much your network or system can handle before it throws a tantrum."

Throughput in information technology refers to the amount of work, data, or transactions a system, network, or application can process in a given period of time. It is a key metric for evaluating performance, capacity, and efficiency of IT infrastructure.

Technically, Throughput involves:

Simple Network Management Protocol

/ˌɛs-ɛn-ɛm-ˈpi/

noun — "the polite protocol that asks devices how they’re doing, then reports back."

SNMP, Simple Network Management Protocol, is a standard protocol used in information technology for managing and monitoring devices on IP networks. It allows network administrators to collect device data, configure network equipment, and receive alerts about operational or performance issues. SNMP is widely used for routers, switches, servers, printers, and other networked devices.

Technically, SNMP involves:
